Let's look at the details provided. + +The problem occurs after upgrading to QEMU 9.1.0, where Linux guests running on an AMD host show new error messages related to machine check exceptions and APIC issues. The user mentioned that bisecting points to a specific commit adding support for the SUCCOR feature in i386, which is required for guests to handle machine check exceptions. + +Looking at the error messages, they all relate to kernel-level issues within the guest OS, specifically mentioning "mce" (Machine Check Exception) and problems with APIC520 LVT offsets. The errors indicate that the BIOS isn't setting up the LVT offset correctly, leading to conflicts when trying to assign vectors. + +Now, considering the categories: +- **Firmware Bug**: This seems relevant because the error messages directly point out issues with the BIOS setup. +- **APIC and Interrupt Handling**: These are part of the firmware/hardware interaction for interrupt management, which is crucial for handling exceptions like MCEs. + +The commit in question adds support for a specific CPU feature (SUCCOR), which allows guests to handle these exceptions properly. However, the errors suggest that without proper BIOS configuration (firmware issue), the APIC vectors can't be set up correctly, leading to conflicts and the kernel messages. + +Therefore, this bug is primarily related to firmware issues, specifically how the BIOS configures the APIC LVT offsets for handling machine check exceptions. +</think> + +The bug report indicates issues with the BIOS configuration affecting APIC vector setup in the guest OS when running under QEMU on an AMD host. This falls under **Firmware Bug** because it relates to incorrect BIOS settings causing hardware-level problems. + +**Answer:** Firmware Bug \ No newline at end of file |
